WebEnergy diagrams for these processes will often plot the enthalpy (H) instead of Free Energy for simplicity. The standard Gibbs Free Energy change for a reaction can be related to the reaction's equilibrium constant (\ (K_ {eq}\_) by a simple equation: ΔG˚ = − RTlnKeq where: K eq = [product] / [reactant] at equilibrium WebA) The reaction is endothermic B) Reactants are located on the flat portion to the left of the peak. Products are located on the flat portion to the right of the peak. The activated complex is located at the peak of the reaction diagram. C) The enthalpy change is +50 kJ D) The activation energy is 200 kJ E) 50 kJ is absorbed in this reaction

WebEnergy profiles usually have potential energy in the y-axis and then reaction progress on the x-axis. So as we move to the right on the x-axis, the reaction is occurring. This first line on our energy profile represents the energy level of our reactants, which are BC and D. So let's go ahead and show the bond between B and C. Web6.7: Energy Diagrams Enthalpy Thermodynamics is the study of the relationship between heat (or energy) and work. Enthalpy is a central factor in thermodynamics. It is the heat content of a system. The heat that passes into or out of the system during a reaction is the enthalpy change.
